To find the voltage at 90 degrees given an instantaneous voltage of 225 V at a 60-degree angle, we can assume a sinusoidal function for the voltage. The voltage can be represented as ( V(t) = V_m \sin(\theta) ), where ( V_m ) is the maximum voltage. Since you provided the instantaneous voltage at 60 degrees, you can calculate the maximum voltage ( V_m ) using ( V_m = \frac{225}{\sin(60^\circ)} ). Then, to find the voltage at 90 degrees, you would evaluate ( V(t) ) at that angle, resulting in ( V(90^\circ) = V_m \sin(90^\circ) = V_m ).
To find the instantaneous voltage of a sine wave at a given angle, you can use the formula ( V(t) = V_{peak} \cdot \sin(\theta) ). For a peak voltage of 100 volts and at 150 degrees, convert 150 degrees to radians if necessary or use the sine function directly. The sine of 150 degrees is 0.5, so the instantaneous voltage is ( 100 \cdot \sin(150^\circ) = 100 \cdot 0.5 = 50 ) volts.
Power in an electric, AC circuit is the product of Volts, Amps, and the Cosine of the angle that separates them. When the Amps lag behind the Volts by 60 degrees, the product of Volts, Amps, and the Cosine of the angle between them provides half the power that would otherwise be available without the 60 degree angle. At 60 degrees, the cosine is 0.5 and at 90 degrees it is zero. So the product of Volts and Amps whenever they are 90 degrees out of phase will result in zero power.
Power factor is the cosine of the phase angle between voltage and current. In a resistive load, current is in phase, i.e. with a phase angle of 0 degrees, with respect to voltage. Cosine (0) is 1.
The angle by which a circuit's current leads or lags its supply voltage.
The firing angle of a phase-controlled rectifier, often denoted as α (alpha), is the angle measured from the zero crossing of the AC supply voltage to the point where the thyristor is triggered or fired. This angle determines the portion of the AC waveform that is allowed to pass through to the load, effectively controlling the output voltage and power. By adjusting the firing angle, the rectifier can regulate the amount of power delivered to the load, with a firing angle of 0 degrees allowing full conduction and higher angles reducing the output voltage.
The instantaneous voltage at 90 degrees in a sinusoidal waveform is at its peak value, as this angle corresponds to the maximum point of the sine function. Mathematically, if the voltage is represented as ( V(t) = V_{\text{max}} \sin(\omega t + \phi) ), at 90 degrees (or ( \frac{\pi}{2} ) radians), the voltage is ( V(t) = V_{\text{max}} ). Thus, the instantaneous voltage is equal to the maximum amplitude of the waveform.
To find the instantaneous voltage of a sine wave at a given angle, you can use the formula ( V(t) = V_{peak} \cdot \sin(\theta) ). For a peak voltage of 100 volts and at 150 degrees, convert 150 degrees to radians if necessary or use the sine function directly. The sine of 150 degrees is 0.5, so the instantaneous voltage is ( 100 \cdot \sin(150^\circ) = 100 \cdot 0.5 = 50 ) volts.
The supplement of an angle is the angle that, when added to the original angle, equals 180 degrees. In this case, the supplement of a 148-degree angle would be 180 degrees minus 148 degrees, which equals 32 degrees. So, the supplement of a 148-degree angle is a 32-degree angle.
A 40 degree angle is the COMPLEMENT of a 50 degree angle.
The complement of an angle is found by subtracting the angle from 90 degrees. For a 47-degree angle, the complement is calculated as 90 degrees - 47 degrees, which equals 43 degrees. Therefore, the complement of a 47-degree angle is 43 degrees.

the degree of a right angle will always be 90 degrees.
It's a 50 degree angle. It's an angle that measures 50 degrees. It's the complementary angle of a 40 degree angle.
The complement of a 40-degree angle is found by subtracting the angle from 90 degrees. Therefore, the complement is 90 - 40 = 50 degrees. This means that a 50-degree angle, when added to a 40-degree angle, will equal 90 degrees.
A 120 degree angle is an obtuse angle. This means that the angle is between 90 and 180 degrees.
The supplement of an angle is found by subtracting the angle from 180 degrees. For a 110-degree angle, the supplement is calculated as 180 - 110 = 70 degrees. Therefore, the supplement of a 110-degree angle is 70 degrees.
The supplement of an angle is found by subtracting the angle from 180 degrees. For a 102-degree angle, the supplement would be 180 - 102 = 78 degrees. Therefore, the supplement of a 102-degree angle is 78 degrees.
